If you wish to contact me, you may do so via the Ubuntu Forums (free registration): Ubuntu Forum Thread. I have a full-time job and a family, and can only support this repository and the related files when I have spare time (infrequently). I do not have time to respond to individual requests unless they are posted publicly, which decreases the number of times I have to answer the same questions and increases the chance that you will get help (because others follow the thread). My email address is not listed for a reason; although it would not take a great deal of effort to find my email address, I will not reply to any messages sent directly to me regarding anything to do with this repository or the Unified Driver.
When posting asking for assistance, you must provide (at a minimum) your printer model, how it is connected, the specific problem, any error messages you see, which driver you are using (and version if the Unified Driver), and how you installed the driver. Without this information, it is unlikely anyone will be able to help you.
Please do read all the relevant sections of this website and the original Ubuntu forum thread post before taking any actions. Many common questions are answered in these locations. If you still have questions after an attempt to find the answer in original forum post, these webpages, and the forum thread, then please do post.
